Abstract

La présente invention concerne un joint d'étanchéité en palier de butée sans évent à élément poreux. Le palier de butée à élément poreux peut comprendre un palier de butée à élément poreux primaire servant également en tant que bague d'étanchéité comprenant un élément poreux positionné au-dessus d'un plénum et un orifice raccordé au plénum, et des passages conducteurs permettant de transmettre un fluide sous pression vers les plénums à travers les orifices de la bague primaire. Le palier de butée sans évent à élément poreux peut également comprendre un gaz de traitement traité fourni vers un orifice qui est le plus proche du gaz de traitement non traité, à une pression qui est supérieure à celle du gaz de traitement non traité. Un gaz (ou un fluide à l'état liquide) inerte peut être fourni vers l'orifice restant, à une pression qui est identique à celle du gaz de traitement non traité. Une certaine quantité de gaz de traitement traité peut s'écouler dans le gaz de traitement non traité, et peut empêcher le gaz non traité d'entrer dans le joint d'étanchéité à élément poreux.
